Question: Each week, Ari buys three dozen eggs and five avocados at his local grocer. This table shows their regular prices this month.
Grocery item Quantity Price ($) Eggs one dozen 4.00 Avocado one 5.00
This week, the grocery store was offering discounts on larger quantities.
Grocery item Quantity Price ($) for this quantity Eggs two dozen 7.00 Avocado three 8.00
How much less did Ari pay for his groceries this week?
1. **State the problem:** Ari buys three dozen eggs and five avocados weekly. We want to find how much less he paid this week with the discounted prices compared to regular prices.
2. **Regular prices calculation:**
- Eggs: one dozen costs $4.00$, so three dozen cost $$3 \times 4 = 12$$ dollars.
- Avocados: one costs $5.00$, so five cost $$5 \times 5 = 25$$ dollars.
- Total regular price: $$12 + 25 = 37$$ dollars.
3. **Discounted prices calculation:**
- Eggs: two dozen cost $7.00$, so three dozen is one two-dozen pack plus one dozen.
- Price for three dozen eggs: $$7 + 4 = 11$$ dollars.
- Avocados: three cost $8.00$, so five is one three-pack plus two single avocados.
- Price for five avocados: $$8 + 2 \times 5 = 8 + 10 = 18$$ dollars.
- Total discounted price: $$11 + 18 = 29$$ dollars.
4. **Calculate savings:**
- Savings = Regular price $-$ Discounted price
- $$37 - 29 = 8$$ dollars.
5. **Answer:** Ari paid $$8$$ dollars less this week due to the discounts.
